(Cl. 72-415) This application is a divisional patent application of cop-ending patent application Serial No. 746,152, filed July 2, 1958, now abandoned.

At present sheet metal barrels are manufactured in a factory where relatively large, expensive and ponderous machines are used in combination with large quantities of sheet metal. Such factory is equipped to manufacture relatively large quantities of barrels. These barrels are transported from such factory by shipments of relatively small numbers of barrels to a plurality of establishments where such barrels are loaded with commodities, after which the covers, which ordinarily have been transported with the barrels, are then secured on the barrels to retain the commodities within the barrels. Such transportation of these barrels from the factory to the establishments is relatively expensive and harmful to the barrels. The barrels are likely to be dented or otherwise damaged by said transportation and the barrels require large transportation vehicles.

The establishments where commodities are loaded in the barrels do not use a sufficient number of barrels to warrant the expense of providing a barrel factory adjacent such establishments, since such a factory would be too expensive, and its output of barrels would be too large with respect to the requirements of the commodity establishment. The barrels transported from the factory to the establishment take up a relatively large amount of space in the transporting vehicles since they must be placed side by side. Such barrels ordinarily are made of 16-18 gauge sheet metal, in order to prevent them from being unduly caved in and otherwise harmed during transportation.

This invention overcomes the foregoing objections by a method whereby a plurality of cylindrical flexible metal barrel bodies are manufactured from 22-30 gauge sheet metal at a barrel factory, or the like, and are nested within a retaining member, which may itself be one of these cylindrical bodies. The nesting is accomplished by inwardly bulging the sides of these barrel bodies progressively deeper to permit the bodies to be nested within each other, and within the container. A number of these nested bodies are then transported to a commodity establishment. Such nested bodies are then unnested at the commodity establishment. A bottom is secured at one end of said bodies, and other steps may be taken to maintain such bodies in the substantially cylindrical form of an unfilled and uncovered barrel. Commodities are then loaded in such unfilled and uncovered barrels, and covers may be secured to the other ends of the barrels to retain the commodities in the barrels. Such a method reduces very materially the expense of transportation between the barrel factory and the commodity establishment. It also prevents the damage to the barrels which is prevalent in the present methods of barrel manufacture and distribution.

This invention also includes relatively simple and inexpensive apparatus to be located and used at the commodity establishment where the commodities are loaded in the barrels. Such apparatus is for the purpose of securing the bottoms to the cylindrical flexible barrel bodies to retain such bodies in cylindrical form and to complete them into unfilled barrels. The apparatus may also perform other steps for rendering the flexible bodies in a firm cylindrical form, and may also include provisions for beading the uncovered end of the barrels more readily to receive the covers which may be secured at that end, after the barrels have been loaded with the commodities.

Hence an object of this invention is to provide apparatus for use at the commodity establishment or other location away from the barrel factory, such apparatus being relatively simple and inexpensive, and which easily and quickly changes the unnested cylindrical flexible barrel bodies into barrels by rendering said bodies relatively rigid and in cylindrical form.

Other objects of this invention will become apparent as the description proceeds with reference to the accompanyin g drawings in which:

FIGURE 1 is a digrammatic elevation of one of the inexpensive machines (a flanging and corrugating machine) for use at the commodity establishment or the like.

FIGURE 2 is an enlargement of portions shown in FIGURE 1 with the flexible cylindrical barrel body ready to be flanged at one end and corrugated into a relatively rigid cylindrical body.

FIGURE 6 is an enlarged vertical elevation, partly in cross-section, of a portion of the apparatus shown in FIGURE 1.

FIGURE 7 is a cross-section taken along the line 2323 of FIGURE 6.

FIGURE 8 is a vertical cross-section of certain parts and taken along the line 2424 of FIGURE 3.

At the commodity establishment or adjacent place, the nested barrel bodies are serially unnested, the innermost one 70 being removed first, etc. Such body is placed in the flanging-corrugating machine shown in FIGURES 18. The body 70, and the other bodies of the nested bundle, are of the correct length to rest between the limiting discs or flanges 111 and 112, FIGURES 1 and 2, preparatory to flanging and corrugating one end of the body in the manner shown in FIGURE 3. The flange 113 and the corrugations 114 are formed in one end 113a of the body 70. Thereafter, such body 70 is removed from the machine and is placed with ends reversed in the same machine, as indicated in FIGURE 4, where the flange 113 is adjacent the disc 111, and the other end of the body 70 is adjacent the flange or disc 115. The machine, in the position shown in FIGURE 4, is operated to produce the corrugations 117, so the barrel body is formed into a semi-rigid, cylindrical barrel body, shown in reduced scale, in FIGURE 5.

The sleeve 126 terminates at 126a (FIGURE 4) to prevent flattening of corrugations 114 While corrugations 117 are being formed.

The flanging and corrugating machine shown in FIG- URES 1-8 includes a power driven shaft 119 driven by a motor, not shown, in the lower part of base 121, such motor being started and stopped by the switch 122 having the starting and stopping push buttons 123 and 123a. The shaft 124 may be an idler shaft. The shaft 119 has a cylindrical sleeve 126, a corrugating roll 127, a second sleeve 128, a third sleeve 129, the flanging disc 115, and the positioning discs 111 and 112. All of these are rigidly secured to the shaft 119.

The shaft 124 has non-rotatable bearing plates and 141 on which a pair of idler rollers 142 are mounted (FIGURE 8). The shaft 124, FIGURE 2, also has the disc 145, corrugating roll 146, and flanging roll 147 rigidly secured to said shaft 124. The plate 141 has a wide flat rod 149 rigidly bolted thereto (FIGURE 8), which in turn is connected to two substantially horizontal rods 150 which straddle the upwardly directed stationary rod 175 and the spring 176 later to be more fully described. The rod 149 and rods 150 prevent the bearing plate 141 from rotating with or around the shaft 124. This maintains the rollers 142 ready to move down on either side of cylindrical sleeve 126 to roll the barrel body 70 into true cylindrical form.

A U-shaped bar 154, FIGURES 2-4 and 8, is supported from any stationary part of the base 121 to maintain the flexible barrel body 70 properly spaced on both sides of the shaft 119.

Referring particularly to FIGURES 6 and 7, the shaft may have a universal bearing 124a on the stationary bearing member 160, FIGURE 6, supported within the base 121 of FIGURE 1. The shaft 124 passes through and has a universal bearing 12412 in the slidable plate 161 which slides within grooves 162 (FIGURE 7) in the stationary upright frame 163 which also has a stationary bearing 164 for the shaft 119. The shaft 119 has a stationary bearing 119a on the bearing member 160, and has a pulley 170 with a chain or belt drive 171 connected to the motor, not shown, in the lower part of the base 121. The wheel or pulley 170 and belt 171 are housed within the protective casing 172, FIGURE 1.

The frame 163, FIGURES 6 and 7, carries an upwardly directed stationary arm 175 to which the spring 176 is connected at its upper end 176a, the lower end 176b being connected to the hook 177 carried by the lever 178 which has a fulcrum bolt 179 in the frame 163, is bolted at 180 to the slidable plate 161, and is connected to the rod 181 which is actuated by the pedal 182 (FIG- URE 1). Downward movement of pedal 182 moves the shaft 124 from the position in FIGURES 1 and 2 to the positions of FIGURES 3 and 4 with sufficient force to form the flange 123 and corrugations 114 and 117 in the body 70. When the pedal 182 is released by the operator, the spring 176 raises the lever 178 and the plate 161 and the shaft 124 from the position of FIGURES 3 and 4 to the position of FIGURES l and 2, so the barrel body 70 may be inserted or removed.

In the operation of the flanging corrugating machine of FIGURE 1, etc., the operator puts the barrel body 70 in the position shown in FIGURE 2. He starts the motor by pushing the button 123. He lowers the shaft 124 to the position of FIGURE 3 by pushing the pedal 182 down. Rotation of the shaft 119 by the motor produces the flange 113 and the corrugations 114 in the barrel body 70, as shown in FIGURE 3. Thereafter, the operator releases the pedal 182, so shaft 124 raises to the position of FIGURE 1. He then reverses the ends of the body 70 to the position shown in FIGURE 4, wherein the flanging disc 115 acts as a limiting means for the end of the barrel body 70, after which he lowers the shaft 124 by means of pedal 182, FIGURE 1, to produce the corrugations 117, FIGURE 4, at the other end of the barrel body 70. The flanged and corrugated body 70 is then removed from the flanging corrugating machine by raising shaft 124 and kicking the body 70 out of the machine. Such body 70 has the finished form shown in FIGURE 5. Preferably, the motor driving shaft 119 is not stopped while reversing the barrel body 70 or while removing such body 70 from the machine or while inserting a new body 70 in the machine. Ordinarily the motor is stopped only at the end of the run.
